Looking back at the development process of the Unified Communication Platform, what do we feel? I just think that the progress of science and technology is confusing. Who once thought that the old beacon was a video exchange? Who once thought that the original fast whip, just for a letter, now a bunch of waves can pass your mind.
Although the Unified Communication Platform has entered our field of view for a certain period of time, what is unified communication. Some people say that Unified comm
telephone services and dial-up Internet services, it directly encapsulates user data and user line signaling in the IP package.
Integrated Access Device (IAD)
IAD provides both analog user lines and Ethernet interfaces for accessing common telephones and computer devices. It is applicable to users who use telephone services and computers to use data services respectively.
The other type of IAD Only provides Ethernet interfaces for accessing computer devices. It is suitable for users who use bot
communication, and give some suggestions to enterprises in terms of purchasing group telephone switches. There are various group telephone systems on the market, analog, digital, and network IP-based products. Which product is truly suitable for the enterprise's own needs? The following items must be considered:
Cost factors: financial conditions, number of internal phone calls within the enterprise, overall cost, whether there are too many long-distance flights in the field, whether there are
different session timer settings.
Connect two terminals with different media capabilities and different SDP messages by reporting in two different control sessions.
To support different network types (V4, V6), and different transmission types, TCP/UDP/sctp/TLS
C. Multi-Point call management
In this scenario, multiple CPE (CPE is the abbreviation of "mermerpremiseequipment", literally referred to as "User front-end device") are connected to b2bua, and b2bua provides services for all CPE.

On October 16, January 27, Avaya held the Asia-Pacific Channel Partners Conference in Beijing. AVAYA was the Global CEO and the New Asia-Pacific president (former president of Beijing Power Asia-Pacific) global and Asia Pacific Technical and channel executives attended the event. AVAYA announced a new product roadmap for integrating the SNE Enterprise Network (NES) in January 19 a week ago: four main product lines: Unified Communication, contact center, small-and medium-sized enterprise communic
In the previous article, we introduced SOA and unified communication, including its overall concept and traffic business. Now we will continue to explain SOA and Unified Communication. First, let's review the four methods of SOA in speech. Then, we will introduce the situation of some products and vendors.
Four Methods of hybrid speech and SOA
Despite the bright future, the market is still in its initial stage, with only four major vendors. Avaya and Siemens work on SOA from the traditional tele
VoIP is a popular technology in the world. Sometimes, when talking about the benefits brought by communication technology, VoIP has won a lot of praise. More and more enterprises are migrating their telephone systems from traditional PBX to ip pbx or IP Centrex of VoIP. The traditional production of PBX is gradually decreasing, and network telephone is becoming t

The platform is positioned between communication infrastructure (such as PBX) and services (such as voice, video, message, video conferencing, and mobility. Thanks to the advantages of Aura, both Avaya and Nort

Since the corporate headquarters typically has a traditional PBX telephone switch, Cisco 3725 is configured as a voice gateway at Headquarters and connected to a PBX through the E1 interface. If the enterprise has a number of branches in the country, each branch
reduced by the ability to transmit voice, video, and data over a converged IP network, the Unified Communication solution can save considerable costs for enterprises.Misunderstanding 3:In today's IP communication field, there is no super powerful application.Actual Situation: enterprises use the Internet for different reasons. similar to this, enterprises use Unified Communication for a variety of reasons. Currently, many Unified Communication applications can reduce costs, increase productivit
communication needs and telephone communication needs. However, because there are multiple independent parallel physical networks, there is no connection between them, the construction and maintenance costs are relatively high, and the O M is difficult.
According to the situation in China, apart from the construction of internal telephone systems by itself in specific industries such as power supply and public security, some of the general enterprises and institutions deploy their own data net
Communication solution runs through a smart phone. The supplier provides a special client software package for each mobile phone, thus limiting the user's choice of the device. If a user is used to a device that the mobile Unified Communication vendor does not support, there will be a huge controversy between the supplier and the user.
Mobile Unified Communication vendor
Mobile Unified Communication vendors can be divided into three categories: Unified Communication vendor, ip
The concept of softswitch was born
The concept of softswitch originated first in the United States. At that time, in the enterprise network environment, users used Ethernet-based phones to implement the PBX function through a set of Call Control Software Based on PC servers ). For such a set of equipment, the system does not need to separately lay the network, but can achieve unified management and maintenance only through sharing with the LAN, the ov
suitable for a wide range of applications, such as home, corridor, desktop, and IP supermarkets. However, IAD is a terminal device, which is inconvenient for management and maintenance.
Through the Access Gateway AG or the FXO port of the integrated access device IAD, the gateway can communicate with the PBX through the AT0 loop relay. The traditional old-fashioned PBX mostly accesses the softswitch networ
